Abstract:
This study sought to examine public support for gun carrying-related policies from 2019 to 2021, a period encompassing the COVID-19 pandemic and increasing calls for racial and social justice. We conducted the National Survey of Gun Policy in January 2019 and 2021. The surveys were fielded using the NORC AmeriSpeak panel. Respondents indicated support for six policies regulating civilian gun carrying. Analyses, conducted in 2021, incorporated survey weights for nationally representative estimates. There were significant declines in support from 2019 to 2021 for two policies that would expand where civilians can lawfully carry guns: allowing concealed carry when on K-12 school grounds (23% in 2021 vs 31% in 2019) and college/university campuses (27% vs 36%). Support was also significantly lower for requiring concealed carry applicants to pass a test demonstrating safe and lawful use (74% in 2021 vs 81% in 2019). For the two new policies in the 2021 survey, more than half of respondents overall supported prohibiting open carry at demonstrations/rallies (54%) and prohibiting the carry of guns into government buildings (69%). There was lower support among gun owners (39% and 57%, respectively). Since 2019, there has been a decline in support for expanding locations for civilian gun carrying. Support remains high among U.S. adults, including the two-thirds of gun owners, for requiring concealed carry applicants to demonstrate competence in safe and lawful gun use. Our findings in support of a more regulated approach to concealed carry are in direct contrast to state-level shifts eliminating concealed gun carrying regulations.
